Research on the Requirement Analysis and Management Method of Aircraft PHM System

Recent years, the forward design based on requirements has become mainstream mode of aircraft and its component systems development. Requirements analysis management not only runs through whole process system development validation activities, but also plays an important role in these activities. However, there are some practical problems requirement prognostics health (PHM) aircraft, such as lack method guidance, incomplete stakeholder analysis, nonstandard description. Therefore, theory engineering, this paper puts basic methods suggestions PHM formulates technical key points demonstration scheme stage, clarifies principles specification. And related research aims to improve quality efficiency system, lay foundation for architecture function well.
